The effect of heat treatment temperature on crystallization behavior of Na2O-Y2O3-SiO2 silicate glass system was studied by melting and crystallization method, and a kind of glass-ceramics containing Na3YSi2O7 crystal phase was obtained. The structure and morphology of the glass-ceramics were studied by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and transmittance. The results show that the average size of 280nm microcrystals can be obtained by holding the precursor glass at 610 °C for 2 h. With the increase of heat treatment temperature from 610 °C to 640 °C, the permeability of glass-ceramics began to decline, and the glass gradually changed into glass-ceramics, and finally emulsified into ceramics. The results show that Na2O-Y2O3-SiO2 silicate glass system is sensitive to temperature, and its microstructure changes obviously in a short time. Therefore, the glass containing Na3YSi2O7 crystal phase is expected to become a new material with high performance, low price and wide application market because of its excellent performance, simple preparation technology and low manufacturing cost.

“…One of current practical solution is to use glass-ceramic materials based on lithium-silicate glasses. This type of material has high visible-range light transmission (72%), high mechanical properties -Vickers hardness HV=8.74 GPa, crack resistance K1C=3.10 MPa×m 1/2 , Young's modulus E=307 GPa and low density ρ=2380 kg/m 3 [2]. It is justification for using it as a base in the production of high-strength materials for protecting optical devices from the effects of high-speed machining.…”

In this work various methods of glass plate hardening are considered. These plates are used to protect defense devices. As a glass was used system R2O-B2O3-SiO2. The method of thermal hardening was considered. Technological disadvantages of this method were discovered by analyzing Newton's rings and a polarizing plate. The use of chemical hardening has shown its advantages over the thermal method. The essence of the method is the ion exchange of alkali metals between glass plates and the chemical mixture melt. The operating principle of the chemical hardening equipment and its technology were considered. As a result, hardened glass plates with preservation of planar geometry were obtained.
